Subject: net/mlx5e: Encapsulate updating netdev queues into a function
Patch-mainline: v5.7-rc1
Git-commit: c2c95271f9f39ea9b34db2301b3b6c5105cdb447
References: jsc#SLE-15172
As a preparation for one of the following commits, create a function to
encapsulate the code that notifies the kernel about the new amount of
RX and TX queues. The code will be called multiple times in the next
commit.
